Project description:To explore the molecular basis by which Id1 loss promotes HSC quiescence under stress we compared the transcriptome of Id1-/- and Id1+/+ HSCs isolated from primary BMT recipient mice by RNA-seq. We found 179 upregulated and 1476 downregulated genes in Id1-/- HSCs compared to Id1+/+ HSCs using a fold-change cut-off of 2 . Collectively, the IPA analysis shows that Id1-/- HSCs have gene expression profiles consistent with reduced response to stress, reduced cycling and proliferation, and reduced ribosomal biogenesis and protein synthesis, which is consistent with our hypothesis that Id1-/- HSCs have molecular signature of quiescent HSCs compared to Id1+/+ HSCs.

Project description:The regulatory circuits that coordinate epidermal differentiation during development are still not fully understood. Here we report that the transcriptional regulator ID1 is enriched in basal epidermal progenitor cells and find ID1 expression to be diminished upon differentiation. In utero silencing of Id1 impairs progenitor cell proliferation, leads to precocious delamination of targeted progenitor cells and enables differentiated keratinocytes to retain progenitor markers and characteristics. Transcriptional profiling suggests ID1 acts by mediating adhesion to the basement membrane while inhibiting spinous layer differentiation. Co-immunoprecipitation reveals ID1 binding to transcriptional regulators of the class I bHLH family. We localize bHLH Tcf3, Tcf4 and Tcf12 to epidermal progenitor cells during epidermal stratification and established TCF3 as a downstream effector of ID1-mediated epidermal proliferation. Finally, we identify crosstalk between CEBPA, a known mediator of epidermal differentiation, and Id1 and demonstrate that CEBPA antagonizes BMP-induced activation of Id1. Our work establishes ID1 as a key coordinator of epidermal development, acting to balance progenitor proliferation with differentiation and unveils how functional crosstalk between CEBPA and Id1 orchestrates epidermal lineage progression.

Project description:Cyclin D1 is a well characterised cell cycle regulator with established oncogenic capabilities. Despite these properties, studies report contrasting links to tumour aggressiveness. It has previously been shown that silencing cyclin D1 increases the migratory capacity of MDA-MB-231 breast cancer cells with concomitant increase in ‘inhibitor of differentiation 1’ (ID1) gene expression. Id1 is known to be associated with more invasive features of cancer and with the epithelial-mesenchymal transition (EMT). Here, we sought to determine if the increase in cell motility following cyclin D1 silencing was mediated by Id1 and enhanced EMT-features. To further substantiate these findings we aimed to delineate the link between CCND1, ID1 and EMT, as well as clinical properties in primary breast cancer. The increase in cell migration following cyclin D1 silencing in MDA-MB-231 cells was abolished by Id1 siRNA treatment and we observed cyclin D1 occupancy of the Id1 promoter region. Moreover, ID1 and SNAI2 gene expression was increased following cyclin D1 knock-down, an effect reversed with Id1 siRNA treatment. Similar migratory and SNAI2 increases were noted for the ER-positive ZR75-1 cell line, but in an Id1 independent manner. In a meta-analysis of 1107 breast cancer samples, CCND1 and ID1 gene expression were associated with mesenchymal-markers including SNAI1, SNAI2 and TWIST1, and with clinicopathological parameters. Finally, a greater percentage of CCND1low/ID1high tumours were found in the EMT-like ‘claudin-low’ subtype of breast cancer than in other subtypes. Together, these results indicate that increased migration of MDA-MB-231 cells following cyclin D1 silencing can be mediated by Id1 and is linked to an increase in EMT markers. Moreover, we have confirmed a relationship between cyclin D1, Id1 and EMT in primary breast cancer, supporting our in vitro findings that low cyclin D1 expression can be linked to aggressive features in subgroups of breast cancer. MDA-MB-231 cells were transfected with cyclin D1, CDK4/6 or control siRNA.

Project description:Metastasis is a major factor responsible for mortality in breast cancer patients. Id1 plays important roles in cell differentiation and promotes tumor angiogenesis, cell invasion and metastasis. Although Id1 is established as a critical factor for lung metastasis in breast cancer, the pathways and molecular mechanisms of Id1 functions in metastasis remains to be defined. Here we show that Id1 interacts with TFAP2A to suppress S100A9 expression. The expression of Id1 and S100A9 is inversely correlated in both breast cancer cell lines and clinical samples. We also find that S100A9 expression rescues the migratory and invasive phenotypes in vitro and metastasis in vivo induced by Id1 expression. S100A9 also suppresses the expression of known metastasis promoting factor RhoC activated by Id1 expression. Our results suggest that S100A9 mediates the functions of Id1 in breast cancer metastasis.

Project description:Id1 and its closely related family member Id3 are expressed by a diversity of stem and progenitor cells. We show that Id1/3 are required for the self-renewal and proliferation of triple negative breast cancer (TNBC) cells both in vitro and in vivo. Furthermore, we identified that Id1/3 negatively regulates the tumour suppressor gene Robo1. Depletion of Robo1 could rescue the proliferative defect induced by Id1/3 knockdown. To understand the mechanisms by which Robo1 rescues cell proliferation in Id1/3 depleted cells, we performed RNA-Sequencing on 4T1 cells with Dox-inducible Id1/3 KD and/or Robo1 depletion using siRNA. We conclude that following Id1/3 knockdown, Robo1 is induced and exerts anti-proliferative effects via suppression of a Myc transcriptional program.
